更换叶轮

Overview: Remove the impeller and install the replacement impeller.

Step 1: Remove the impeller cap

Using a small flat-blade screwdriver or other similar tool, pry the cap loose from the impeller.

Step 2: Remove the impeller

Removing the flat bearing below the Form Wash V2 impeller

The impeller is secured by one screw with a washer. Use a 2 mm hex driver to remove the screw. Remove the washer, the impeller, and the flat four-lobed bearing below the impeller. Set the components aside for disposal.

Step 3: Install the replacement impeller

Installing the flat bearing under the Form Wash V2 impeller

The wash bucket has an engraved depression shaped to hold the flat four-lobed bearing. Place the new bearing into this depression. Insert the new impeller into the wash bucket. Align the impeller’s screw hole with the corresponding screw hole in the wash bucket. The impeller should sit flat against the bottom of the wash bucket.

Step 4: Reinstall the impeller screw

Place the washer onto the impeller’s screw hole. Thread the screw into the Form Wash impeller’s screw hole. Using a 2 mm hex driver, tighten the screw until finger tight. Take care to not overtighten or strip the plastic threads in the wash bucket.

Step 5: Check impeller spin

Spin the impeller by hand. It should spin freely. If it does not, loosen the screw half a turn and check again. Repeat as needed.

Step 6: Mount the impeller cap

Align the posts on the impeller cap with the grooves of the impeller. Gently press the impeller cap into place.

完成修复

Overview: After installing the new impeller, power on the machine and perform final checks.

Step 1: Refill the wash bucket

Refill the wash bucket to your desired fill level.

Step 2: Reinstall the inner lid

Align the front edge of the inner lid with the wash bucket’s edge and lower the inner lid directly into the top of the wash bucket.

Step 3: Reinsert the wash bucket

Insert the wash bucket into the Form Wash.

Step 4: Lower the elevator

Turn the Form Wash knob to select Lower on the display. Push the knob to confirm. The Form Wash lowers the elevator and basket into the wash bucket.

Step 5: Test the repair

Turn the knob to navigate the display menu and set the Time. Push the knob to select or confirm. Select Start. Check to see that the wash cycle starts normally and that the Form Wash does not make any unusual noises and that the impeller is moving properly.
